Atmel brings the solution to applications where fast computing is as mandatory as low consumption, such as aerospace electronics, portable instruments, or embarked systems. AT60142E AT60142ET Utilizing an array of six transistors (6T) memory cells, the AT60142E/ET combine an extremely low standby supply current (Typical value = 65 µA) with a fast access time at 15 ns over the full military temperature range. The high stability of the 6T cell provides excellent protection against soft errors due to noise. The E version is biased at 3.3 V and is not 5V tolerant: it is available to 15(1) and 20 ns specification. The ET(1) version is a variant allowing for 5V tolerance: it is available in 17 ns and 20 ns specification. The AT60142E/ET are processed according to the methods of the latest revision of the MIL PRF 38535 or ESA SCC 9000. It is produced on a radiation hardened 0.25 µm CMOS process. Note: 1.

See Figure 1 Figure 1. AC Test Loads Waveforms Data Retention Mode Atmel CMOS RAM's are designed with battery backup in mind. Data retention voltage and supply current are guaranteed over temperature. The following rules insure data retention: 1. During data retention chip select CS must be held high within VCC to VCC -0.2V. 2. Output Enable (OE) should be held high to keep the RAM outputs high impedance, minimizing power dissipation. 3. During power-up and power-down transitions CS and OE must be kept between VCC + 0.3V and 70% of VCC. 4. The RAM can begin operation > t R ns after VCC reaches the minimum operation voltages (3V).
